Description

Descending grades with trailers can be hazardous and tricky situations, resulting in over heated service and trailer brakes, that leads to brake fade, excessive wear, and costly unwarranted repairs. BD Engine brake has been the industries time proven VARIABLE REGULATING BACK-PRESSURE EXHAUST BRAKE.

How it works: Using BDs exclusive Variable butterfly Technology, providing peak retarding power throughout the engines rpm range unlike some models that rely on a hole/orifice within the butterfly to calibrate back-pressure only in the higher engine RPM .

Where it mounts: Most vehicle applications will either have BDs turbo-mount design which bolts in place of the factory elbow between the turbo and the exhaust system or the inline design mounts in the exhaust system between the engine and muffler/DPF/cat.

For modified Turbo and engine applications: Got a modified or twin-turbo application? BD offers a remote mount exhaust brake that incorporates all of our standard technology found in our turbo mount units in a 4 free flowing design that wont impede the exhaust flow and performance enhancements you worked so hard to achieve.

The advantage to regulating the butterfly vs. other brands is: The Butterfly is constantly exercising thus reducing the possibility of carbon and rust deposit forming that can cause premature ware and binding. Furthermore no maintenance or lubricating is required providing miles of trouble free service.

Stainless steel butterfly shaft that has proven to stand up under the harsh, high-heat conditions of the exhaust environment, the offset butterfly valve wont stick, and has been strategically placed in the elbow so that it wont impede exhaust flow when in the open position.
Brake valve is actuated by an air cylinder (newer models) or a powerful, three-inch vacuum cylinder (earlier models). The durable air compressor included in later model kits can even be used for other applications, such as air horns, air bags even air-ride fifth wheel hitches its that tough.
